Well ,. i have to dissagree with the 18's. It is not very real-world... Think, you are going to have a 35 profile. One pot hole or ledge in the road and kiss you wheels good bye. Plusif you are modifying it for racing or better handling, having 18 would not be very senseable.They are going to scrub like a bitch. I recomend 17. on a 205/40 series tire. I do agree with the coil-overs, if you can afford them. But if not just go with a good set of springs like from Eibach and a set of good shocks.(pref- adjustables)
